[glamor] GL_ARB_buffer_storage causes corruption under X11 and XWayland
on a Radeon RX550 using Fedora Rawhide (But also tested on F30 stable) on an ARM64 system I would see drawing corruption only on GTK apps under X11.
After a bit of debugging I traced the allocation back to glamor_vbo.c, and then tested by starting the Xwayland session with MESA_EXTENSION_OVERRIDE=-GL_ARB_buffer_storage , which has resolved the issue. Obviously this is not the correct fix as this functionality works fine with QT based apps.
